WG Review Announcement

From: The IESG <iesg-secretary@ietf.org>
To: "IETF-Announce" <ietf-announce@ietf.org>
Cc: sipcore@ietf.org 
Subject: WG Review: Session Initiation Protocol Core (sipcore)

The Session Initiation Protocol Core (sipcore) WG in the Applications and
Real-Time Area of the IETF is undergoing rechartering. The IESG has not
made any determination yet. The following draft charter was submitted,
and is provided for informational purposes only. Please send your
comments to the IESG mailing list (iesg@ietf.org) by 2016-11-20.

Session Initiation Protocol Core (sipcore)
-----------------------------------------------------------------------
Current status: Active WG

Chairs:
  Jean Mahoney <mahoney@nostrum.com>
  Adam Roach <adam@nostrum.com>

Assigned Area Director:
  Ben Campbell <ben@nostrum.com>

Applications and Real-Time Area Directors:
  Ben Campbell <ben@nostrum.com>
  Alissa Cooper <alissa@cooperw.in>

Charter: https://datatracker.ietf.org/doc/charter-ietf-sipcore/

  The Session Initiation Protocol Core (SIPCore) working group is
  chartered to maintain and continue the development of the SIP protocol,
  currently defined as proposed standard RFCs 3261, 3262, 3263, 3264, and
  6665.

  The SIPCore working group will concentrate on specifications that
update
  or replace the core SIP specifications named above as well as
  specifications pertaining to small, self-contained SIP protocol
  extensions.  The process and requirements for new SIP extensions are
  documented in RFC5727, "Change Process for the Session Initiation
  Protocol".

  Throughout its work, the group will strive to maintain the basic model
  and architecture defined by SIP. In particular:

  1. Services and features are provided end-to-end whenever possible.

  2. Reuse of existing Internet protocols and architectures and
     integrating with other Internet applications is crucial.

  3. Standards-track extensions and new features must be generally
     applicable, and not applicable only to a specific set of session
     types.

  4. Simpler solutions that solve a given problem should be favored
      over more complex solutions.

  The primary source of change requirements to the core SIP
specifications
  (enumerated above) will be a) interoperability problems that stem from
  ambiguous, or under-defined specification, and b) requirements from
  other working groups in the ART Area. The primary source of new
protocol
  extensions is the DISPATCH working group, which will generally make the
  determination regarding whether new SIP-related work warrants a new
  working group or belongs in an existing one.
